Johanna Konta has parted company with her coach Esteban Carril at the end of a year in which she made her debut in the world's top 10.
The 25-year-old has not commented yet, but Carril confirmed to the BBC that the partnership has come to an end.
Konta has been training in the Spanish city of Gijon with Carril and Jose-Manuel Garcia for the past two years.
The British number one is now preparing for the new season at the National Tennis Centre in Roehampton.
